About

Bradley Greger is a pioneering figure in neuroprosthetics and brain-machine interfaces (BMIs), whose work has fundamentally advanced the restoration of motor control and sensory feedback for individuals with paralysis or limb loss. His research centers on decoding high-level cognitive signals from the brain and creating bidirectional interfaces with the peripheral nervous system. Greger’s landmark 2004 study demonstrated that neural prosthetics could decode not just hand trajectories, but cognitive control signals related to movement goals—a conceptual leap that has garnered over 660 citations. In a highly impactful 2016 study (332 citations), he showed that arrays of 96 microelectrodes implanted in the median and ulnar nerves could restore both motor control and sensory feedback in people with upper extremity amputations, enabling intuitive control of advanced prosthetic limbs. More recently, Greger has contributed to next-generation BMI hardware, developing soft, stretchable bilayer electrode arrays that independently record neural signals while conforming to brain tissue. His work bridges fundamental neuroscience and clinical application, offering tangible hope for patients with severe motor disabilities.
